A person loses consciousness when either the blood flow through the brain or when the nerve messages through the brain are disrupted. A shock or extreme accelleration can cause a part of the brain stem called the Reticular Activating System to temporarily shut down, causing you to black out. It is quite common that when this occurs there is no accompanying concussion.

haha....burn.
